I don't understand how, or why, people try to analyse physical action as a political or philosophical act, I'm not sure everyone involved in it does at any rate. Even if you believe that
some Fash or fellow travellers can be talked to and brought back from where they are (and I do) that's a moot point when it comes to actual, street level action. The only question there is what effect their presence on a community and what measures are needed to limit it, I don't understand how anyone with any experience of the world can honestly try to break that down into a comfortable political talking point to be chewed over with sorry recriminations from a safe distance. When these people go out to march, or more usually just act up in their day to day lives, they're not setting out to convert people, or convince people of their righteousness, they're trying to assert their power, they do it solely to make themselves feel bigger and to intimidate and threaten the people around them. Saying
no violence in return as a personal position might feel morally right to an individual, it might even
be morally right to an individual but it's still a myopic position and a selfish one to impose on other people.
Try to impose the same thinking on others, imagine it's your family, your friends or your kids who are walking around that area when the Fash are out. Imagine it's them being told they deserve to die, that they're less than human, that they should be lynched or thrown in gas chambers. Imagine that it's them being physically attacked for the colour of their skin, or their religion or for believing that Fash thinking is wrong. And that'll all happen even without them being involved in any counter protest, it'll happen just because they exist. It happens every day in fact. To condemn people who take physical action in return, or who defend those who are attacked in that way is, tbh, a fucking disgusted moral imposition to make on anyone especially if you're taking your stand from a safe distance where you're fairly sure you won't face the same.
Look at what
bimble posted from that member of the clergy, that's a decent position for any pacifist to take if they hold their beliefs honestly. You don't have to fetishise violence or think it's good or get a buzz off of it. You just have to accept that your moral stand (if that's really what it is) isn't viable or reasonable for everyone and perhaps even acknowledge that, if it were, it wouldn't just be the philosophically peaceful counter-protestors who'd get a beating for it. If Fash felt they could act with impunity on the streets, whenever and wherever they are, it'd be whole communities who'd have to live with it. Day in and day out.
